[LLVMdev] New machine model questions
...ult but I don't know how much of a reduction I can expect at the moment.
I'm not sure I fully understand the super-resource suggestion. I've attached my WIP so you can take a look at the code in context but the relevant extracts are below.

[LLVMdev] New machine model questions
Hi Andrew,
I seem to be making good progress on the P5600 scheduler using the new machine model but I've got a few questions about it.
How would you represent an instruction that splits into two micro-ops and is dispatched to two different reservation stations?
For example, I have two reservation stations (AGQ and FPQ). An FPU load instruction is split into a load micro-op which is
